Revival fire–that’s it! God stir us to pray, “Oh that You would rend the heavens! That You would come come down! That mountains might shake at Your presence–as fire burns brushwood, as fire causes water to boil–to make Your name known to Your adversaries, that the nations tremble at Your presence!” (Isaiah 64:1-2 NKJV).
